hi, in your example data = {{1, {38, 35, 37}}, {2, {21}}, {3, {24, 14}}} I would use a rule of the form data /. {j_Integer, k_List} :> Thread[j -> k] to get {{1 -> 38, 1 -> 35, 1 -> 37}, {2 -> 21}, {3 -> 24, 3 -> 14}} best, christoph On 04/04/2012 10:31 AM, clansa wrote: > Hello, > I have these data > {{1, {38, 35, 37}}, {2, {21}}, {3, {24, 14}}} > and I want > {[1->38,1->35,1->37},{2->21},{3->24,3->14}} > The solution is simple when list of data have the same length > But what is the solution for my example > Thanks > > Andrew >
